LACING STUD OR HOOK.

SPECIFICATION forming part of Letters Patent No. 538,428, dated April30,1895.

Applicati n file January 24, 1895. Serial No- 536,013- (No model.) I

To all whom it may concern:

Be it known that I, EDWARD MAYNZ, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Lacing Studs or Hooks, of which the following is aspecification.

This invention relates to metal lacing studs or hooks and has particularreference to that type having heads provided with a covering of anysuitable composition adapted to be applied in a plastic state and toharden in place.

The object of this invention is to provide a sheet metal lacing hook orstud having its head practically covered with composition so far as theexternal appearance of the stud is concerned, but which provides a metalwearing surface around the edge of the head.

A further object of the invention is to provide a construction wherebythe under side of the composition-covered head is protected by themargin of the metal portion of thehead, and is left flat so as to offerno obstruction to the insertion or removal of the lacing cord.

To these ends the invention may be said to consist in the sheet metallacing stud or hook having a dome-shaped perforated head-portion, and arecessed under side, and an inner and outer covering of compositionconnected together through said perforation and anchored on thedepressed under side.

In the accompanying drawings, forming a part of this application, Figurel is a side elevation of the improved lacing stud or hook. Fig. 2 is asectional view of the same on a vertical plane passing through the bowof the hook. Fig. 3 is a sectional view of the stud or hook before thecovering is applied.

The metallic portion of the stud or hook is formed in the usual way, ofsheet metal, to constitute the neck, I), the head or top portion, 0, andattaching means such as prongs, a.

Heretofore, when such studs have been made to be covered withcomposition, the head, 0, has been flat, thus causing the composition onthe under side of the head to bulge below the head and present a convexsurface which is an obstruction to the fre passage of the lacing cord. V

In the improvement herein shown, the head, 0, is formed dome-shaped withone or more perforations, c, This enables the composition, 01, which isapplied to the head in the usual way, to anchor on the depressed undersurface and to be fiat on its under side, or level with the edge of thesaid head, the composition above and below the dome-shaped head beingconnected through the perforations and thereby held in place. Thisconstruction presents a metal surface, viz: the edge of the head, 0, tothe wearing action of the lacing cord when inserting or removing thelatter, and prevents the liability of the breaking away of thecomposition by said cord. Furthermore, as above stated, on the underside of the head of the hook there is no convex obstruction to the freepassage of the lacing cord, the under surface of the composition beingflat. Said under surface is, moreover, surrounded and protected by themargin of the metal head.

I do not confine myself to the pronged construction shown and may applymy improvement to a hook or stud having a tubular eyelet.

Having now explained the nature of my invention and described a way ofconstructing and using the same, though without attempting to set forthall of the forms in which it may be made or all of the modes of its use,what I claim, and desire to secure by Letters Patent, is

A lacing-stud or hook comprisinga domeshaped perforated metal headhaving a recessed or concave under side, and a coating of compositioncovering the convex upper side of the head, extending through theperforation in the head, and anchored in the concave under sideofthehead, the said coating having a flat under surface which issurrounded and protected by the margin of the head.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 21st day of January, A. D.1895.
